Lancelot (The Theriot Family #3)
Silvia Violet

Then I met Julian.
I wanted to hate him. He's my opposite in every way. I'm impulsive, and there's no rule I won't break. Persnickety Julian follows every rule.
But when I make demands and he stands his ground, I know he will be mine.
To win him over, I'll have to do the impossible, prove that occasionally, I can be reserved and restrained.
